The Future of
Weld Seam Inspection
Has Arrived.

VITRONIC WSI is joining LMI Technologies.

Proven Precision/Global Scale/Unmatched Support

We’ve joined forces to deliver the world’s most comprehensive 3D vision and inline weld inspection ecosystem.

LMI Technologies is proud to announce the acquisition of VITRONIC’s industry-standard Weld Seam Inspection (WSI) business. For decades, automotive leaders have trusted VIRO WSI, Weldloop, and WSI Visualization to guarantee flawless weld quality. Now, combined with LMI’s world-leading 3D sensor innovation and global support network, the future of weld inspection is stronger than ever.

What’s Ahead

Built to Get Even Better

As WSI integrates with the LMI platform, customers gain access to capabilities that build on the system they already trust.

Expanding Global Support & Logistics

WSI customers will gradually gain access to LMI’s worldwide service network across the Americas, Europe and Asia, with more local spare parts, more field engineers and faster response times as the network grows.

A Shared Roadmap for R&D & AI

WSI’s welding expertise and LMI’s 3D sensing and deep-learning technology will be developed together, with the goal of even more accurate defect classification in future releases.

Toward a Unified Sensor & Software Ecosystem

Over time, WSI will connect more closely with LMI’s broader sensor and software portfolio, opening new options for factory-wide quality management and automated production lines.

Measurement & Detection Capabilities

Weld Seams,
Measured in 3D

VIRO WSI captures the 3D surface geometry of each inspected seam inline, checks every feature against tolerance, and flags surface defects before parts move downstream.

The weld

A production seam with surface pores — easy to miss by eye at line speed.

02

3D height map · VIRO WSI

The VICT sensor captures the seam’s true 3D shape and defines its outline and evaluation region.

03
